Participants

Reaction Steps

(2-{4-[(2R)-2-Amino-3-(4-chlorophenyl)propanoyl]-piperazinyl}phenyl)-N,N-dimethylcarboxamide HCl salt was prepared according to the procedure described in Preparation XVI by using [2-(4-{(2R)-2-[(tert-butoxy)carbonylamino]-3-(4-chlorophenyl)propanoyl}-piperazinyl)phenyl]-N,N-dimethylcarboxamide (Step 4) (240 mg, 0.46 mmol) and a satd soln of HCl in EtOAc (10 mL). The white solid that formed was isolated by filtration (200 mg). MS (ESI, pos.ion) m/z: 415 (M+H). Calc'd for C22H28Cl2N4O2: 451.39.
